QuestionQ12

Perform DR and Data Protection in a Multicloud Environment

An administrator is attempting to move an asynchronous protection domain (PD) workload from one cluster to another by leveraging PD-Based DR, and Prism displays the following error message:

> Error updating protection domain. Protection domain is already active on source site "cluster name". Please trigger migrate from source site to activate the protection domain.

What would cause this error to appear?

  • A VMs must be migrated from the VM page instead of using DR
  • B Must “Promote” the secondary site first before activating
  • C Must “disable” first before trying to activate a PD
  • D Trying to “activate” the PD while the primary cluster is reachable
Explanation

This error occurs because 'Activate' is intended for unplanned failover scenarios where the source site cannot be reached to deactivate its protection domain, whereas 'Migrate' is the correct operation for planned failovers where the source cluster is still reachable — it deactivates the PD on the source and activates it on the destination in a single, orchestrated step. Attempting to 'Activate' the PD on the destination while the source cluster is still up and the PD remains active there triggers Prism's safeguard error, prompting the administrator to use 'Migrate' instead.
